Embryo type:
Spatulate fully developed.
Seed collecting:
Pick heads that are maturing, drying off, with brown seeds that dislodge easily.
Seed cleaning:
Place the seed-heads in a tray and leave to dry for a week. Then gently rub the heads by hand to dislodge the seeds. Use a sieve to separate the unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
Seed viability:
From two collections, the seed viability were low to high, ranging from 45% to 90%.
